The names of the bones that comprise the auditory ossicles are taken from Latin. The malleus translates to the "hammer," the incus is the "anvil," and the stapes is the "stirrup." Ossicles which are present in the middle ear, are made of three tiny bones that have their own separate names and characteristics. Their Latin etymology might be a result of their appearance or the way they look. These names are namely, malleus or hammer, incus or anvil and stapes or stirrup. Inside the middle ear, three small bones (ossicles) form a chain and conduct sound vibrations from the eardrum to the inner ear.

This study was performed to evaluate the usefulness and limitations of three-dimensional (3-D) imaging of the ossicular chain in the middle ear by high speed helical CT. One dissected human temporal bone, five normal ears, and twelve diseased ears (trauma, ossicular anomaly, cholesteatoma, chronic otitis media) were scanned in 1.0mm slices and reconstructed at a thickness of 0.2-0.5mm. Pharyngeal arches form the main anatomical structures of the head and neck, including all components of the middle and outer ear. The three middle ear bones or auditory ossicles ( malleus, incus, stapes) are formed from the cartilage template found within pharyngeal arch 1 and 2.
